Separator



Patented Dec. 9, 1941 SEPARATOR Albert E. Winslow, New London, Conn., assignor to Atwood Machine Company, a corporation of Connecticut Application July 1, 1941, Serial No. 400,627

4 Claims.

This invention relates to a ring spinning or twisting frame, more particularly to the thread guard or separator between the rings of the frame.

In ring spinning or twisting, the balloon of the thread as it travels about the spindle, if uncontrolled, would materially limit the distance between the rings. Accordingly, some guard to prevent one thread from hitting another thread is inserted, and the rings brought closer together. Such guard is frequently termed a separator. The separator must be supported and be sufiiciently stiff to be self-sustaining when engaged at an edge. Quite frequently these separators are mounted from below; or a rod is provided with a groove in which the separator is set; or various other relatively complicated ways are provided for holding the separator in place.

One of the objects of this invention is to provide a simple yet effective full length separator.

Another object of the invention is to provide a separator which will be stiffened and all of a single piece of sheet metal.

Another object of the invention is to provide a separator so shaped that it may be supported in a simple and efiicient manner.

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. l is a perspective view of the separator and a clamp therefor;

Fig. 2 is a section through the clamp.

The spinning frame which this invention is designed to operate provides rings supported in a manner to project outwardly from the ring rail as more fully shown in my application Serial No. 366,671, filed November 22, 1940. The separators are positioned between these rings and extend the full length of the spindle. This separator is formed of a single piece of stock stifiened on its edge by merely rolling this stock, the rolling being placed symmetrical with the plane of the sheet stock. I

With reference to the drawing, designates a sheet of stock which provides the separator. The

stock is rolled as at H into a cylindrical tube, the edge l2 being in abutting relation at the point it where it is deflected at an angle to the plane of the body of the separator 10. This provides a closed tube and so stiifens the separator lengthwise that it cannot be easily bent.

The tubular portion ll provides sufficient enlargement so that the separator may be readily gripped at any point along the full length of this tube being clamped, designated generally l5. The clamp consists of two parts I6 and I1 providing gripping jaws to engage the tube H. A bolt [8 having a slotted head l9 and a nut 20 will draw the jaws together into gripping engagement on the tube II.

This separator may be made of light, nontarnishable material, such as aluminum or some alloy thereof, and be relatively easy to handle and one which will not impart any soil to the thread being operated upon.

I claim:

1. A separator to be positioned between yarn spindles comprising a blade having one of its longitudinal edges rolled into a closed hollow formation, to provide a bearing through which said separator is secured in place.

2. A separator to be positioned between yarn spindles comprising a blade having one of its longitudinal edges rolled into a closed, tubular portion to provide a bearing through which said separator is secured in place.

3. A separator to be positioned between yarn spindles comprising a blade having one of its longitudinal edges rolled into a closed tubular portion and positioned symmetrically with reference to the opposite faces of the blade to provide a bearing through which said separator is secured in place.

4. A separator to be positioned between yarnspindles comprising a blade having one of its longitudinal edges rolled into a closed cylindrical tubular portion and positioned symmetrically with reference to the opposite faces of the blade to provide a bearing through which said separator is secured in place.
